System and method for diagnosing lung disease by computer

Abstract

The invention relates to a system and method for diagnosing lung disease by a computer. The diagnostic system comprises a first training unit, a second training unit, a segmentation unit, and an assessment unit, wherein the first training unit is used for generating an average lung shape model based on a plurality of first figure X-ray image samples; the second training unit is used for generating at least one lung area classifier model for classifying characteristics of the lung disease based on a plurality of second figure X-ray image samples; the segmentation unit is used for generating a lung field image through segmenting a to-be-diagnosed figure X-ray image and based on the average lung shape model; the assessment unit is used for comparing the lung area classifier model with the lung field image to analyze the characteristics of the lung disease in the to-be-diagnosed figure X-ray image.

Description

technical field [0001] The invention relates to a computer diagnosis system and method, in particular to a computer diagnosis system and method for diagnosing lung diseases such as pneumoconiosis. Background technique [0002] Pneumoconiosis is an occupational disease mainly caused by lung tissue fibrosis caused by long-term inhalation of a large amount of fine dust. According to authoritative statistics, pneumoconiosis is one of the most serious occupational diseases in my country. It is also a disease that seriously reduces labor capacity, disables and affects life expectancy. [0003] At present, the diagnosis and staging of pneumoconiosis are mainly based on X-ray chest films with good imaging quality. On the premise of having a definite history of occupational dust exposure and a certain amount of dust exposure, the chest radiograph is an absolute basis for the diagnosis and differential diagnosis of pneumoconiosis. At present, the first choice for the diagnosis of pne...

Problems solved by technology

First of all, personnel engaged in the diagnosis of pneumoconiosis must pass the national occupational disease (pneumoconiosis) diagnostic physician qualification examination and obtain a qualification certificate, which limits the scope of medical treatment to a certain extent and brings inconvenience to patients, especially for some economically backward areas; Second, the film quality of the X-ray chest film to be diagnosed must meet certain standards. For example, the X-ray chest film must ensure that the photo has no artifacts, light leakage, pollution, scratches, water stains and low foreign object influence (mor
